USSD or Unstructured Supplementary Service Data is a session-based text-messaging service that does not require sending SMS and instead is activated by entering a particular code on the dialler screen. These codes trigger specific telecom-based services such as balance information, caller tunes activation, internet usage details, and call forwarding. Since these services are provided by the telecom operator, there is no need to an app.

However, in recent times, this feature has been misused by cybercriminals. Multiple reports have found that fraudsters impersonated customer care representatives from the victim's bank or telecom operator, and would get them to dial the 401 call forwarding code, followed by a number that was already in the hands of the scammers.
